Изучена мясная продуктивность чистопородных и помесных бычков ½ калмыцкая и ½ казахская белоголовая породы. Установлено, что убойная масса помесных бычков была больше, чем у чистопородных на 14,16 кг или 5,41 % (Р&gt;0,99). В связи с этим у помесного молодняка убойный выход в сравнении с чистопородными бычками выше на 0,51%.</p></abstract><trans-abstract xml:lang="en"><p>The article examines the meat productivity of Kalmyk bulls of different genotypes in the Uralan Agrofirm of the Priyutnensky district of the Republic of Kalmykia. The meat productivity of purebred and crossbred bulls of the Kalmyk and Kazakh white-headed breeds has been studied. It was found that the slaughter weight of crossbred bulls was greater than that of purebred bulls by 14.16 kg or 5.41% (P&gt;0.99). In this regard, the slaughter yield of crossbred young animals in comparison with purebred bulls is higher by 0.51%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морфологический состав туш</kwd><kwd>выращивание</kwd><kwd>откорм</kwd><kwd>убойная масса</kwd><kwd>убойный выход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>morphological composition of carcasses</kwd><kwd>cultivation</kwd><kwd>fattening</kwd><kwd>slaughter weight</kwd><kwd>slaughter yield</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Амерханов, Х.А.
